Add USB option in machine options
When -usb option is used, global varible usb_enabled is set. And all the plaform will create one USB controller according to this variable. In fact, global varibles make code hard to read. So this patch is to remove global variable usb_enabled and add USB option in machine options. All the plaforms will get USB option value from machine options. USB option of machine options will be set either by: * -usb * -machine type=pseries,usb=on Both these ways can work now. They both set USB option in machine options. In the future, the first way will be removed. Signed-off-by: Li Zhang <zhlcindy@linux.vnet.ibm.com> Acked-by: Alexander Graf <agraf@suse.de> Signed-off-by: Alexander Graf <agraf@suse.de>
